MCI error--what is it?

    I just bought a program called Movie Talk Spanish that runs an interactive
    teaching program from a DVD-ROM after setting up a few files on the hard
    drive. Everytime I try to run any part of this program it gives me the
    following error message and won't run:

    "MCI Error: Unknown problem while loading the specified device driver"
    There are Abort and Ignore choices, neither of which helps.

    I have an ASUS MB, P4, 500mb RAM, 12x DVD drive, XP Pro, Media Player 9, the
    latest drivers for video, the latest DirectX, all the fixes for the Indeo
    drivers missing from SP1, everything, in other words. I can double click on
    the large MPG files on the DVD and they play perfectly. DVD movies play
    normally. It's just the parts of this particular program that use these MPG
    files that won't run. I've uninstalled and reinstalled the program several
    times, uninstalled the DVD software as directed. And I had a 45 minute tech
    support call with Microsoft--no help.
    I have done everything suggested by the software's tech support site.

    The program, incidentally, works /perfectly on my laptop/, also with XP SP1.

    Can anyone think of a reason why this "driver", whatever it is, won't load?
    How do you troubleshoot MCI errors? I can't see any driver or other file
    except for the exe program file that gets loaded, even on my laptop when the
    program is running.

    Uh. Trouble-shooting MCI isn't a lot of fun.
    First key is likely:
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI32
    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\MCI
    Movie Talk Spanish is either trying to go through the MPEGVideo driver from
    MCI32 (that should be mciqtz32.dll) or ... I'm not sure what under MCI.

    Sorting through a registry watcher may help show things further, but: I'd
    just call it a day and use Movie Talk Spanish on the working system...

    Incredible! It was so easy once I knew what to do, and now I'm kicking
    myself for not having thought to look there myself. :)

    I went to the registry and found that under MCI32 the MPEGVideo and
    MPEGVideo Keys had values of a file called MCIFMP32.DLL and there was
    another key that had ReelMagic. A quick Google search showed that the
    MCIFMP32.dll was from the old ReelMagic program from Sigma--something I
    vaguely recall having several years ago. I no longer have that MCIFMP32.DLL
    file anywhere on my computer, so of course the program couldn't find it when
    it wanted to play an MPEG or MPEG2 file. I suspect the registry key was left
    over from an old hard drive I transferred over or an XP upgrade. That should
    teach me to install clean every time. The other computer in which Movie Talk
    Spanish worked of course had the correct mciqtz32.dll keys for MPEG and

    Needless to say, the program now works perfectly on this computer since I
    changed the registry.

    Thank you very much!! I am going to forward this on to the program publisher
    so that the next person with a similar problem won't go through this.
